Bibliography print the first author's name flipped

[seveathers]

After \printbibliography, the order of the first author's name in the output pdf is always different from the other authors. And a comma is added in between makes it looks like two people. Is this a feature or a bug? Is there any way to turn off this flipping?

I have found where the style is defined in cls. Sorry I didn't read the cls before asking. I thought I cannot understand it. But in the end it is not that difficult to read. I will close this.

By the way, I really like your work. It is beautiful.
